The population structure of North Atlantic fin whales has been investigated since the start of whaling operations but is still the subject of an ongoing scientific debate. Here we measured stable isotopes of carbon, nitrogen and oxygen in skin samples collected from 151 individuals from western Iceland, Galicia (NW Spain), the Azores archipelago and the Strait of Gibraltar (SoG). We found spatiotemporal differences in stable isotope ratios suggesting that fin whales sampled in these four areas may share a common feeding ground within the Northeast Atlantic at different times during the year. Our results also suggest that SoG whales use this common feeding ground in summer but exploit Mediterranean resources during the winter months, further supporting the existence of a limited but current exchange of individuals between these two basins This work, including collection of samples from the Azores, was supported by Fundação para a Ciência e a Tecnologia (FCT) [IF/00943/2013/CP1199/CT0001, UID/MAR/04292/2019 to MARE, IF/00943/2013 to M.A.S., IF/00029/2014/CP1230/CT0002 to A.C., SFRH/BPD/108007/2015 to R.P.] and by Fundo Regional da Ciência e Tecnologia (FRCT) and Azores (2020) Operational Programme [WATCH IT - Acores-01-0145-FEDER-000057] through FEDER, COMPETE, QREN, POPH, FSE, and the Portuguese Ministry for Science and Education.
